description:
- cast ident argument because it is usually an fd (signed) and generates
  conversion to unsigned warnings.
While here:
- name the macro parameters with meaningful names
- rename the internal inline function as _FOO instead of FOO_ because there
  is no other FOO_ name in the system headers.
